It compares HybridBridge with alternative methodologies, highlights its superiority and outlines potential applications. The HybridBridge employs two independent geometry parameters to facilitate optimal flow mapping while maintaining physically accurate effective thermal conductivity and ensuring high mesh quality. A method is proposed to estimate the HybridBridge radius for a defined packed bed and cap height, enabling a presimulative determination of a suitable radius. Numerical analysis of a body-centered-cubic unit cell with varied HybridBridges is conducted alongside previous simulations involving a simple-cubic unit cell. Additionally, a physically based resistance model is introduced, delineating effective thermal conductivity as a function of the HybridBridge geometry and porosity. An equation for the HybridBridge radius, tailored to simulation parameters, is derived. Comparison with the unit cells and a randomly packed bed reveals an acceptable average deviation between the calculated and utilized radii, thereby streamlining and refining the implementation of the HybridBridge methodology.<\/jats:p>","DOI":"10.3390\/computation12050089","type":"journal-article","created":{"date-parts":[[2024,5,2]],"date-time":"2024-05-02T08:42:57Z","timestamp":1714639377000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Analysis of a Novel Method for Generating 3D Mesh at Contact Points in Packed Beds"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-4945-5945","authenticated-orcid":false,"given":"Daniel F.","family":"Szambien","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Kraftwerkstechnik und W\u00e4rme\u00fcbertragung, Gottfried Wilhelm Leibniz Universit\u00e4t Hannover, An der Universit\u00e4t 1, 30823 Garbsen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-2308-6612","authenticated-orcid":false,"given":"Maximilian R.","family":"Ziegler","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Kraftwerkstechnik und W\u00e4rme\u00fcbertragung, Gottfried Wilhelm Leibniz Universit\u00e4t Hannover, An der Universit\u00e4t 1, 30823 Garbsen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1901-9542","authenticated-orcid":false,"given":"Christoph","family":"Ulrich","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Kraftwerkstechnik und W\u00e4rme\u00fcbertragung, Gottfried Wilhelm Leibniz Universit\u00e4t Hannover, An der Universit\u00e4t 1, 30823 Garbsen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5128-5291","authenticated-orcid":false,"given":"Roland","family":"Scharf","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Kraftwerkstechnik und W\u00e4rme\u00fcbertragung, Gottfried Wilhelm Leibniz Universit\u00e4t Hannover, An der Universit\u00e4t 1, 30823 Garbsen, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,30]]},"reference":[{"key":"ref_1","unstructured":"(2012).
